Touchscreen Region Enlargement Superimposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display resolution increases in information processing devices, objects such as characters and icons become smaller, reducing visibility, and existing solutions do not effectively address this issue by allowing users to easily enlarge specific regions on the screen.
Innovation Solution
An information processing apparatus that includes a display device, a coordinate input device, and a processor, which allows users to designate a region for enlargement by inputting coordinates on the touch panel or touchpad, generating an enlarged image at a predetermined magnification, and superimposing it on the original image, ensuring the enlarged region fits within the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display resolution is increased, then display quality and sharpness are improved, but visibility of objects such as characters and icons deteriorates
Solution Approach 1:
The display is segmented into a full-screen view and an enlarged region view. The processor divides the display into a first display region showing the full image and a second display region showing an enlarged portion, allowing users to access both the overall context and detailed visibility simultaneously.
Solution Approach 2:
The patent introduces a dimensional transition from two-dimensional full-screen display to a layered three-dimensional display structure. By superimposing the enlarged image over the original image at different visual layers, the system creates a new dimension of interaction that resolves the visibility issue without sacrificing the original display quality.
2Manufacturing precision
If display resolution is increased, then image sharpness is improved, but the size of objects on screen decreases
Solution Approach 1:
The system dynamically adjusts the display configuration based on user input. When a user designates a region of interest, the processor dynamically switches from displaying the full-resolution image at its original size to displaying an enlarged version of the selected region, allowing objects to appear larger while maintaining the sharpness of the high-resolution source.
3Ease of operation
If existing enlargement solutions are used, then visibility of specific regions can be improved, but operation complexity increases
Solution Approach 1:
The system uses the display device itself as the coordinate input device. Users interact naturally by touching or pointing at the display screen to designate regions for enlargement, eliminating the need for separate input devices or complex control sequences. The display serves dual purposes: showing the image and receiving user input.

AI summary
An information processing apparatus includes a display device configured to display a first image, a coordinate input device configured to input coordinates on the first image, and a processor configured to perform processing based on input to the coordinate input device. The processor specifies a part of a region on the first image as a specific region, based on coordinates of two points that are input to the coordinate input device, generates a second image that is obtained by enlarging the specific region at a predetermined magnification, and causes the display device to superimpose and display the second image on the first image with the second image occupying a part of the first image.
